-What type of pump should be used for a calcium chloride aqueous solution at 20 degrees with a density of 1.18?
Thread Content
As the title suggests, the issue regarding the choice of material for calcium chloride solution
Please specify the concentration (chloride ion concentration) and temperature
Concentration? Service life? Usage requirements?
-20 degrees is ice; the pump can’t be used. It’s just for fun
What is the calcium chloride concentration? Are there particles in the solution? If there are particles, a polyethylene version is also an option; if there are no particles or only a few, a fluorinated lining centrifugal pump can be chosen.
How do I read this table? I don’t understand
Is this a calcium chloride solution at saturation? Do you know the properties of calcium chloride solution? It has five key properties. 1. Alkaline nature: Calcium ions cause hydrolysis that results in an alkaline environment, while hydrogen chloride is volatile after the hydrolysis of chloride ions. 2. Conductivity: There are ions in the solution that can move freely. 3. Freezing point: The freezing point of a calcium chloride aqueous solution is lower than that of water. 4. Boiling point: The boiling point of a calcium chloride aqueous solution is higher than that of water. 5. Evaporation crystallization: The evaporation crystallization of calcium chloride aqueous solutions must take place in an atmosphere filled with hydrogen chloride. Calcium chloride tends to crystallize easily at low temperatures; if open impellers are a concern, a mortar pump made of ultra-high molecular weight polyethylene with semi-open impellers could be considered, as these facilitate the transportation of materials.
Alkaline calcium chloride is easy to use, but care also needs to be taken when using the bushings.
The freezing point of calcium chloride at 1.18 is -17.4; in this case, heating is required to maintain its temperature
